Abstract
A sensor (1) has a movable element (11) which when moved to one operating position, defines a space for containing resins (10). Sensor detects volume changes of quantity of resins, after starting one of the restoration phases. When the detected value reaches a preset threshold, an interrupt signal for supply of water flow to the resins is generated, so that the softening capacity of the resin is restored. The duration of the restoration phases and the quantity of water utilized during them are in function of reaching actual restoration of softening capacity of the resins. During restoration phases, water is supplied to the resin in association with a regenerating agent, for regenerating the resin. Independent claims are also included for the following: (a) Control method of water hardness reducing system; (b) Resin volume change detecting device; (c) Household washing machine
